宇宙事物千姿百态,发展过程中,千变万化;变是绝对的,不变是相对的,绝对不变的事物未之有也。任何事物,总是随其内外关系存在矛盾的斗争与统一,此消彼长,由不平衡到平衡;如此循环往复、螺旋运动,由甲状态到乙状态,由不合理到比较合理,由低级到高级,贯穿事物演变始终。实际上是无始无终,永不停息。易理精髓、道经真谛、辩证学说,庶近此理。社会事物的宏观现象、微观状态亦复如此,成为规律。王安石所谓“天变不足畏,祖宗不足法,人言不足恤”亦近此理。 The things in the universe are mixed in different forms and manifestations. In the process of development, the ever-changing one is changing; the one that changes is absolute, the same is invariant, and the absolutely unchanged thing does not. Everything is always contradictory with its internal and external relations struggle and unity, counterbalanced, from unbalance to balance; this cycle of reciprocating, spiral movement, from A state to B state, from unreasonable to more reasonable by the low To advanced, throughout the evolution of things has always been. In fact there is no beginning and no end, never stop. The essence of Yi Li, Taoist truth, dialectical theory, Shu nearly this principle. The macro phenomenon of social things, the micro state is also the case, become a law. Wang Anshi’s so-called “days are not afraid, ancestors less than law, people say less than shirt” is also close to this.
